Dr. Naresh Thadhani
Naresh Thadhani is Professor and Chair of the School of Materials Science and Engineering (MSE) at Georgia Tech (GT), which includes 38 faculty and ~370 undergraduate and ~185 graduate students. He joined the GT faculty in 1992, after six-years in the Center for Explosives Technology Research at New Mexico Tech, and two years as a post-doc at CalTech. He was appointed as the School Chair on August 1, 2012, two years after MSE merged with the former School of Polymer, Fiber, and Textile Engineering. He received his B.E. in 1980 from the Malaviya National Institute of Technology in Jaipur, India, M.S. from South Dakota School of Mines, and Ph.D. from New Mexico Tech, all in Metallurgical Engineering.
Professor Thadhani is recognized for his work in shock-compression and high-strain-rate deformation of materials. His research has focused on the fundamental mechanisms of shock-induced physical, chemical, and mechanical changes under high-pressure shock-compression, and the deformation and fracture response of metals, ceramics, polymers, and composites, subjected to ballistic impact and high-strain-rate loading. He has led significant advancements in the understanding of shock-induced phase transformations and mechanical properties of bulk metallic glasses; design, development, and characterization of structural energetic materials, and the shock-compression response of highly heterogeneous (granular) materials through meso-scale computational simulations and experimental studies with meso-scale spatial and nano-second resolution temporal diagnostics.
Professor Thadhani has advised 15 visiting scientists/post-docs; 29 Ph.D and 14 M.S degree students; mentored 50+ undergraduate researchers. He has attracted research funding exceeding ~$17M from federal agencies including the AFOSR, ARO, DARPA, DTRA, ONR, NSF, as well as from several national DoE and DoD laboratories and industries. He has co-edited 12 books/proceedings, published more than 300 papers in refereed journals (including several invited review articles) and conference proceedings, and presented more than 150 invited talks/seminars. He has served or is serving on review boards including the National Academy of Science panel at the Army Research Laboratory (2015 and 2016), academic program review at Universities of Texas at Austin and El Paso, University of Notre Dame, University of Florida, and the University of California multi-campus national lab collaborative research program review, and external advisory board of Materials Science and Engineering program at the University of Texas at Dallas. He has provided high levels of service to professional societies, and organized numerous workshops/symposia/conferences.
Professor Thadhani is a Fellow of ASM International and the American Physical Society. He was recently elected as an Academician of the EuroMediterranean Academy of Arts and Sciences.

She completed her BS in Materials Science and Engineering (magna cum laude) at the University of Florida. Holguin is passionate about medical technology and biotechnology to improve healthcare for society. She has vast experience with interdisciplinary collaboration with chemical, materials, mechanical, and biomedical engineers. She is currently working with Prof Naresh Thadhani and Prof Mark Prausnitz to study intracellular drug delivery using laser-activated nanoparticles. This physical drug delivery method is a platform for gene delivery and cancer treatment.
Holguin is actively involved in outreach for underrepresented groups and mentoring of young STEM students. In her spare time, she enjoys traveling, muay thai kickboxing, and trying new foods. Holguin has been recognized with a number of prestigious fellowships, including the National Science Foundation Graduate Research Fellowship, the Alfred P. Sloan Foundation & NACME Minority PhD Scholar, and the National Institute of Health Biomaterials Training Grant.
Travis J. Voorhees
Travis is originally from San Diego, CA, and completed his undergraduate degree in Chemical Engineering at Cal Poly Pomona, where he competed as a decathlete and pole vaulter on the Track and Field team. Travis currently studies the dynamic consolidation of brittle cerium dioxide powders by conducting both impact experiments using the 80 mm light gas gun at Georgia Tech and cylindrical implosion experiments using the pulsed power driver PHELIX at Los Alamos National Laboratory. Travis is also a collaborator with the Prausnitz Lab, conducting laser exposure experiments to support drug delivery research being conducted by Stefany Holguin and Simple Kumar.
Travis is actively involved with the MSE Graduate Student Advisory Group and helps to run the Graduate Recruitment Fair and other social events in the MSE department at Georgia Tech. Travis is also involved with NACE International and is nominated as the 2018 Vice Chair of TEG 331X at the NACE Corrosion 2018 Conference & Expo. When not doing research, Travis is a children’s backpacking guide in the Sierra Nevada mountain range, leading elementary and middle school students on 30 to 120 mile trips with the Poway Backpackers nonprofit organization.
Andrew Boddorff is currently a first year Ph.D. candidate in the Material Science and Engineering School at Georgia Tech. After graduating from Hamilton College in 2010 with a degree in Chemistry, Andrew joined DC Teaching Fellows to become an educator and enter the classroom with the intent of serving the vulnerable student populations in the nation’s capital. Andrew joined the faculty at Ballou SHS and worked for five years as a Chemistry teacher and eventual department chair.
The love of science that he passed onto his students eventually lead him to return to the lab, joining Dr. Thadhani’s group. He intends to work on understanding how the structure of additively manufactured materials affect shock properties through laser shock and gas gun experiments. Beyond the lab, Andrew enjoys physical activities such as hiking and Ultimate Frisbee as well as cerebral pass times, such as board games.
